SRAM RED crankset is a lightweight and high performance, component that uses hollow construction all the way to the spider. A hidden bolt pattern makes more use of carbon fibre further increasing the stiffness of the crank yet still shedding weight.

This Shimano Dura Ace FC-R9100 HOLLOWTECH II Crankset (2x11-speed) is wider than its predecessor but is still very lightweight by utilising the Hollowtech II technology. The highly rigid hollow structure cuts down on weight but still maintains strength resulting in better power transfer and more precise front shifting.
